Question 700697
<font face="Times New Roman" size="+2">


In a linear equation, ALL of the terms have a degree of 0 or 1.  Anything else is non-linear.  Note:  A constant term, that is a term containing no variable, is a degree zero term.  The degree of a term is the sum of the exponents on all variable factors in that term.  So *[tex \LARGE x] is a 1st degree term (no exponent is understood to be an exponent of 1), but *[tex \LARGE xy] is a 2nd degree term because the SUM of the exponents is 1 + 1 = 2.  Also, any variable in a denominator of a rational expression has a negative exponent.  For example, *[tex \LARGE \frac{1}{x\ -\ 2}] is a non-linear term.
